1 Claim.

This invention relates to a non-refillable bottle, the general object ofthe invention being to provide simple means whereby the non-refillablemeans can be placed in the neck of the bottle below the mouth thereof sothat a cork or other sealing medium can be used, the inventionpermitting liquid to be poured from the bottle but preventing liquidbeing poured in the bottle and such means also preventing the devicebeing rendered inoperative through means of a wire or the like.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout theseveral views, and in which:

Figure 1 is a vertical sectional view through the neck of a bottleprovided with the invention.

Figure 2 is a top plan view of Figure 1, and

Figure 3 is an exploded view of the various parts of the non-refillablemeans.

Referring to the drawing, the letter A indicates the neck of a bottleand in carrying out the invention a groove I is formed in the neck anappreciable distance from the top thereof so that a cork or othersealing means can be used for closing the mouth of the bottle. Anannular bead 2 is also formed in the neck below the groove. A cylinder 3having a reduced cylindrical end 4 is placed in the bottle and aring-shaped seal 5 of rubber, cork or the like is placed over the part 4and fits snugly the internal wall of the bottle neck below the groovewith the end of the part 4 and part 5 resting against the bead. Theupper end of the part 3 is formed with notches 6. The upper end of thepart 4 where it joins the bottom of the part 3 is formed with anupstanding bead 'l which forms a seat for a valve disk 8 which islocated in the par-t 3. A shell 9 has its top closed and its bottom openand the sides of the shell are formed with the" tongues it which areprovided by making substantially inverted U-shaped cuts in certain partsof the device and these tongues are bent outwardly, as the parts arepressed in place, as shown in Figure 1, so that these tongues will havetheir upper ends engaging the top wall of the groove i so that the partsare locked in the mouth of the bottle. Vertical grooves or recesses Hare formed in the sides of the shell between the parts having thetongues formed thereon and each part II will space portions of the shellfrom the internal walls of the bottle neck but they will not expose theparts having the tongues Ill therein so that these tongues cannot bereached by a wire or the like in an attempt to remove the device fromthe bottle neck. A slight depression i2 is formed in the central part ofthe top of the shell to form a seat for the valve 8 when the bottle isinverted so as to prevent the valve from sticking or being held to thetop of the shell so that the valve will dropback upon the bead i whenthe bottle is placed in upright position again.

From the foregoing it will be seen that after the parts are put in placeas shown in Figure 1 they are firmly held in place and cannot be removed and after the cork or sealing member has been removed and thebottle inverted liquid will flow therefrom past the valve 8 which isunseated, due to the partial inverting of the bottle and then thisliquid will pass through the notches 6 into the shell 9 and then throughthe openings formed by the tongues H] into the groove l and then theliquid will pass through the recesses H into the bottle mouth and thusbe poured from the bottle. As soon as the bottle is put in uprightposition again the valve 8 will drop upon its seat I and thus preventany liquid from being poured into the bottle. If an attempt is made tohave liquid enter the bottle by placing the same in a supply of liquidwith the bottle inverted the pressure of the liquid will move the part 8upon the seat l.

Thus it will be seen that I have provided a simple device for renderinga bottle non-refillable.

As will be seen the bottom of the groove slopes downwardly and inwardlyand when the shell 9 is pressed into place the lower ends of the tonguecarrying parts will be forced inwardly and downwardly by this angularlower part of the groove so that the tongues Ill will be automaticallymoved into the groove as shown in Figure 1. This device could be put inplace with a bottle filling machine.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended claim.

Having described the invention, what is claimed as new is:

In a bottle having an neck, the groove having a annular groove in itsdownwardly and inwardly sloping bottom wall, a valve seat forming ingadapted to fit over the valve carrying pa: member of tubularconstruction looated in the and the ends of the tongue carrying partsbein neck and a valve for engaging the seat and movpressed downwardlyand inwardly when the shel able oif the seat when the bottle is tiltedinto is pressed into place. by the angular bottom 0 pouring position, ashell having its bottom open 5 the groove, to move the tongues into thegroov and the sides having grooves therein and tongue for locking theshell in place.

carrying parts between the grooves, said shell be- OLIVER. H. LEE.
